+> Application basée sur Node.js et Express 4 qui envoie des datagrammes TUIO en fonction des touch-events récupérés sur une page web
 
+
 
+## Description
 
+
 
+Le projet fourni est composé de 2 parties:
 
+* un backend
 
+* un frontend
 
+
 
+Le backend est une application Node.js basée sur Express; il officie comme émetteur de données TUIO qui sont récupérées à chaque touch-event.
 
+
 
+Le frontend est une page web, servie par le backend, qui envoie les touch-events au backend via requête HTTP.
 
+
 
+Chaque partie est contenue dans le dossier correspondant.
 
+
 
+
 
+## Pré-requis
 
+
 
+* Installer Node.js (v16 ou v17)
 
+* Installer les dépendances:
 
+
 
+```sh
 
+cd receiver
 
+npm install
 
+```
 
+
 
+
 
+## Lancer le serveur
 
+
 
+Dans le dossier du projet, lancer la commande suivante:
 
+
 
+```sh
 
+node ./backend/server.js
 
+```
 
+
 
+* La page du frontend sera accessible à l'adresse http://localhost:5001
 
+* Le serveur envoie les messages TUIO sur le port UDP 3333.
 
+
 
+
 
+## Gestion de la "section" d'identifiants de points
 
+
 
+Utiliser le paramètre d'URL `section` pour déterminer la "tranche" dans laquelle les identifiants de points seront compris, par exemple: http://localhost:5001?section=10000
 
+
 
+Idéalement, ne pas utiliser des centaines, après quelques minutes de tests, des identifiants supérieurs à 200 pouvaient déjà être notés, d'où l'exemple avec 10000.

+> Application basée sur Node.js et Express 4 qui reçoit des datagrammes TUIO et les transmet à une page web via web-sockets
 
+
 
+## Description
 
+
 
+Le projet fourni est composé de 2 parties:
 
+* un backend
 
+* un frontend
 
+
 
+Le backend est une application Node.js basée sur Express; il officie comme récepteur de données TUIO et les renvoie vers le frontend au moyen d'un web-socket.
 
+
 
+Le frontend est une page web, servie par le backend, qui reçoit les événements émis par le serveur grâce au web-socket.
 
+
 
+Chaque partie est contenue dans le dossier correspondant.
 
+
 
+
 
+## Pré-requis
 
+
 
+* Installer Node.js (v16 ou v17)
 
+* Installer les dépendances:
 
+
 
+```sh
 
+cd receiver
 
+npm install
 
+```
 
+
 
+
 
+## Lancer le serveur
 
+
 
+Dans le dossier du projet, lancer la commande suivante:
 
+
 
+```sh
 
+node ./backend/server.js
 
+```
 
+
 
+* La page du frontend sera accessible à l'adresse http://localhost:5000
 
+* Le serveur écoute les messages TUIO sur le port UDP 3333.
 
+
 
+## Tester la réception de messages TUIO
 
+
 
+On utilise le simulateur TUIO pour envoyer des messages. Par défaut, celui-ci émet également sur le port UDP 3333.
 
+Ce simulateur a été inclus à la racine du projet.
 
+
 
+Sur GNU/linux, le simulateur peut être lancé avec la commande suivante:
 
+
 
+```sh
 
+java -Djavax.accessibility.assistive_technologies=" " -jar TuioSimulator.jar
 
+```
 
+
 
+Note: le laguage Java doit être installé sur la machine.
 
+
 
+
 
+
 
+## État des lieux
 
+
 
+Lors de la réception des messages TUIO, la page web calcule la distance entre chaque point enregistré (via théorème de Pythagore), et l'affiche en console (!! la console du navigateur, accessible via F12 sur la page web).
 
+
 
+C'est à partir de ces distances entre points qu'on pourra déterminer si ils font partie d'un même groupe. Cette partie là n'est finalement pas fournie ce soir...
